“I do not have sex for money!” smokin’ FDNY beat-down transsexual Claudia Charriez insisted to a Manhattan assault jury today, on her second day of testimony against hunky hose handler Taylor Murphy.

“I escorted men who like girls like myself,” the shapely she-male told jurors, when confronted with her nude photographs from a pornographic escort service advertisement — still online, as first reported in The Post today.

“Whether I chose to engage in sexual activity with someone, protected, was my choice,” the pre-op transexual cried on the witness stand in Manhattan Supreme Court, waving her manicured hands.

Charriez is accusing Murphy of slugging, biting and choking her during a heated love spat at a Midtown hotel last year. Yesterday, on her first day on the stand, she conceded that she has worked as an escort since age 14, but swore she stopped as of the Fall of 2011.

Charriez’s ad, which is still live on transgay.com under Charriez’s escort name, “T.S. Taylor,” features two full-length nude photos of Charriez, along with text boasting of her 34D-22-34 measurements and her $400-an-hour “out-call” rate.

When defense lawyer Jason Berland, handed her a screen shot from the ad, her jaw dropped.

“I’ve never seen this before! Where did you get this!” she shrieked, outrage in her voice.

Charriez was brought to tears several times in the day’s testimony — including when the prosecutor asked her about any “hormone therapy” she may have been under at the time of the alleged assault.

“I don’t need to take hormone therapy — because at a very young age I was castrated!” she sobbed.

At another point in her testimony, on direct examination by prosecutor Kevin Rooney, Charriez sobbed that because of trial publicity she’s been barred by her family from visiting her youngest relatives. “They won’t let me spend Christmas which them because of this!” she cried.

Later, when the defense lawyer mentioned a deceased ex-boyfriend, Charriez burst into honking, masculine sobs. Jurors were led out of the courtroom, and then Charriez turned to the defense lawyer and shouted in a mannish voice, “You shouldn’t talk about dead people!”

Charriez’s testimony was halted almost before it got started today, when a woman in the young audience stood up, holding up copies of today’s tranny-vs-firefighter stories in the Post and the News, along with a copy of the 2011 un-official FDNY calendar in which Murphy posed shirtless as “Mr. March.”

“I love you Taylor!” the woman shrieked before fleeing the courtroom and the building, muttering, “I can’t help it — I get emotional.”

“It’s someone I know,” Murphy said, waving his hand dismissively, when asked later who the woman was.

The outbreak brought Charriez to gasping sobs on the witness stand, and Manhattan Supreme Court Justice A. Kirke Bartley ordered a recess, during which he said he planned to reprimand the shouting spectator.

The mystery woman, however, could not be found.

“Should there be any further breach of decorum of this court — anyone who is looking to spend the holidays at Rikers Island, this would be the perfect vehicle to accomplish that,” the judge warned the audience when court was back in session.

Murphy’s defense had planned to call a surprise witness today — convicted millionaire Upper East Side madam Kristin Davis, who met Murphy at a fund-raiser when she ran for governor. But Charriez’s star turn on the witness stand wound up taking the entire day.

Davis told The Post last night that she has been subpoenaed by the defense to testify about a disturbing phone exchange with Charriez from just months before the alleged August 2011 hotel-room assault.

“I don’t need crazy, nutso trannies in my life!” Davis told The Post. “She called me a million times from a blocked number, and when I finally picked up, she was in a very agitated and irate state,” Davis recalled.

“She was demanding, ‘Do you have a relationship with him? Let me tell you what an awful guy he is.’

“I told her please don’t call me again, but a few hours later, she called back and said ‘I’m calling the police and I’m going to give numbers of all of Taylor’s friends, including yours to the police.’

“A few months later, I read about his arrest in The Post,” said Davis, whose testimony could cut both ways — Murphy also harassed her, she said, repeatedly emailing her and banging on the door of her Upper East Side apartment to beg her to write a letter detailing Charriez’s threatening phone call.

“I don’t want anything to do with his weird sexual proclivities either,” she said. “I don’t want anything to do with either of them!”
